What is Physical Access Control Systems?

The security offered by physical access controls could be a solution considered. In the following lines, we will look at what physical access control is, and why it is a good solution for your business when it comes to access control protocol and security.


What is Physical Access Control?

Physical access control is a security system that allows you to restrict and manage access to physical locations or resources. PACs encompass a range of components and technologies designed to grant or deny entry based on an individual’s credentials, time, and authorization level.

Components of Physical Access Control Systems

Access Points

Access points are the entry or exit locations controlled by the PACS. These may include doors, turnstiles, gates, or any other physical barriers that can be electronically managed.

Identifying Personal Credentials

Users of Physical Access Control must have a means of identifying themselves in order to be granted access to the Area he is entitled to. Different identification methods include ID badges, cards, mobile apps, PINs, passwords, QR codes, biometrics, and license plate recognition for vehicles.


Readers are the devices that receive and validate the credentials. They collect the data then communicate them to the control panel and grant or deny access based on the information provided.

Control Panel

The control panel is the brain of a Physical Access Control System. They process the data sent by the readers and enforce access policies. When data of a credential is approved then access is granted. In the case the data are denied then the access will not be granted at the access point.

Different Types of Physical Access Control Authentication Methods

Authentication methods determine how individuals prove their identity to gain access.

Cards or Key Fobs

Users simply present their access cards or key fobs to the reader, which collects the card data to validate their credentials and grants or denies access accordingly. They are an easy and fast solution however it’s not always possible to check who the cardholder is. If an unauthorized person gets hold of an employee’s card, they’ll be able to access restricted areas.

Mobile Phones

Mobile phones can be used as a form of physical access control security, using an app with NFC or QR code technology.

Phones make entry rights easily configurable for different users and different entry points.

Unfortunately, like cards and fobs, with mobile phones, you cannot know at 100% who access the restricted area.
